The set-up for the electorn ring long confinement on the small radius in a heavy ion collective accelerator prototype

The results of the experimental verification of the electron ring long confinement on the small radius in a collective accelerator are presented. The set-up of the magnetic field formation are described. The magnetic coils of the electron ring compressor are closed by diode crow-bar commutator. The decrement of the magnetic field is ∼ 35 ms. The lifetime of the electron ring on the small radius of ∼ 10 ms
